The increase in the potential for rain in parts of Indonesia, according to the BMKG, was influenced, among other things, by the presence of cyclonic circulation and convergence/confluence areas.

The BMKG said that the cyclonic circulation observed in the southern waters of West Java and the Pacific Ocean north of Halmahera formed an elongated wind speed deceleration area in parts of Java, the Indian Ocean south of Banten-West Java, and North Maluku.

Convergence areas were also observed extending from North Sumatra to Aceh, from Jambi to South Sumatra, northern Sulawesi, West Papua, and Papua.

Meanwhile, wind confluence areas (confluence) were observed in the Indian Ocean south of Java and the Pacific Ocean east of the Philippines.

The presence of cyclonic circulation and convergence/confluence areas can increase the potential for rain cloud growth around the cyclonic circulation area and along the convergence/confluence area.
